This is a mash-up of a spring pea salad and an Italian chopped salad—with a hat tip to the distinctly American invention of the three-bean salad—and is bedecked with lots of chewy, crunchy, creamy, salty, and juicy things to bite into. If you can get a variety of beans and peas, terrific. If you can only find one or two, that’s fine—aim for a total weight of 2 pounds and it will all work out.
